Abstract

Titanium and its alloys have widely been used in orthopedic and dental applications due to their good corrosion resistance, good mechanical strength and low density. However, Ti alloys are bioinert when implanted in the body. To overcome this drawback and in order to improve their bioactivity properties, Hydroxyapatite (HA) coatings have been deposited on the surface of the Ti alloys using different synthesis strategies. In the present study, hydroxyapatite-Cu and hydroxyapatite-CuO nanocomposite coatings with different percentages of Cu and CuO (10, 20 and 30 wt.%) were deposited on Ti6Al4V using electrophoretic deposition (EPD). The surface morphology, composition, and microstructure of the nanocomposite coatings were investigated by scanning electron microscopy (SEM), and X-ray diffractometry (XRD), respectively. In addition, corrosion behavior coatings on Ti6Al4V in solution simulated body fluid at 37◦c test was evaluated by polarization. Polarization test results showed that the applied coating improves the corrosion resistance of the substrate. HA-CuO coatings for corrosion resistance as well as greater coverage of the HA-Cu.
